There was a package called paradox which had more features
on the package UI.  It included a command
paradox-commit-list that opened a buffer showing one line
per commit with the commit message and a button that was a
link to the commits diff.  It bolded the commits since the
current installed version to make it easy to see the
changes.  It only worked on github hosted packages.  It
would be great to have this functionality in package.el
particularly if it worked on non-github hosted packages.
